Notes for Figure 33 − Figure 40
1.
For common vent, vent connector sizing and vent material, use
the NFGC.
2.

connector outside furnace casing when 5−in. (127 mm) vent
connector is required, refer to Note 1 above.
3.
Side outlet vent for upflow and downflow installations must use
Type B vent immediately after exiting the furnace, except when
the Downflow Vent Guard Kit, is used in the downflow position
4.
Type−B vent where required, refer to the Note 1 above.
5.
A 4−in. (102 mm) single−wall (26 ga. minimum) vent must be
used inside furnace casing and when the Downflow Vent
Guard Kit is used external to the furnace.
6.
Accessory Downflow Vent Guard Kit is required in downflow
installations with lower vent configuration.

START−UP, ADJUSTMENT, AND SAFETY
Step 1 —General
!
FIRE HAZARD
Failure to follow this warning could result in personal
injury, death and/or property damage.
This furnace is equipped with manual reset limit
switches in the gas control area. The switches open
and shut off power to the gas valve if a flame rollout or
overheating condition occurs in the gas control area.
DO NOT bypass the switches. Correct inadequate
A03219
combustion air supply problem before resetting the
switches.
!
CUT HAZARD
Failure to follow this caution may result in personal
injury. Sheet metal parts may have sharp edges or
burrs.
Use care and wear appropriate protective clothing,
safety glasses, and gloves when handling parts and
servicing furnaces.
1. Maintain 115−v wiring and ground. Improper polarity
A02068
will result in flashing a status code 10 and no furnace
operation.
2. Make thermostat wire connections at the 24−v terminal
block on the furnace control. Failure to make proper
connections will result in improper operation. (See
Figure 26)
3. Gas supply pressure to the furnace must be greater
than 4.5−in. w.c. (0.16 psig ) but not exceed 14−in. w.c.
(0.5 psig).
4. Check all manual−reset switches for continuity.
5. Install blower compartment door. Door must be in place
to operate furnace.
6. Replace outer door.
Step 2 —Start−Up Procedures
!
FIRE OR EXPLOSION HAZARD
Failure to follow this warning could result in personal
injury, death, and/or property damage.
Never purge a gas line into a combustion chamber.
Never test for gas leaks with an open flame. Use a
commercially
specifically for the detection of leaks to check all
connections. A fire or explosion may result causing
property damage, personal injury or loss of life.
1. Purge gas lines after all connections have been made.
2. Check gas lines for leaks.
